Summary
Pineapple cannery effluents are available nearly round the year. The effluents are rich in microbially utilizable nutrients and when supplemented with ammonia support good growth of Candida utilis and Hansenula sydowiorum.
The latter strain produces 45.0 g/l, 21.9 g/l, 1.5%, and 6.4% of cell biomass, protein, DNA, and RNA respectively in batch fermentations of such a medium. Amino acid profile, digestibility, NPU, and actual feed experiments confirm the applicability of the product. Concomitantly, a 90% reduction in BOD5 value of the effluent can be effected during this process which otherwise proves to be troublesome.
